I might be interested in this; seems similar to something I took part in ages ago, on an account that has since been lost to the internet for eternity (or until something jogs my memory).

Don't have much ideas for a character now, but I'm leaning towards perhaps some minor noble from a land farther away in the area for their own reasons. Something like a wildcard sort of character (or spanner-in-the-works, depending on how you look at it) who's simultaneously bystander and unintentional - mostly - hindrance/boon.
